i was sitting here playingnot 20 min ago, and my 2 week old elixer g strring broke near the bridge. this is the second string (first one was a stock with my yamaha)that has broken there in the same spot on the same string. is this a problem with my bridge or whats up??? this wasnt a cheep set for a poor little student like me. what should i look at doing if it is a problem with the bridge?
